Harken Winches: Maintenance Kits & Maintenance Accessories

For Harken winches, there are typically service kits for regular maintenance (e.g., cleats & springs, seals/O-rings, stripper rings) as well as repair/overhaul kits for heavily used components (e.g., bearings/roller bearings, selected gear parts). For sport and regatta use, pawls/springs and proper lubrication are often the most important factors; for cruising, seals, bearing condition, and corrosion protection are also key.

The model, size, and series of the Harken winch are decisive. This information is often found as an embossed mark or type designation on the drum or base. Alternatively, an exploded view or parts list can help. The quickest way to identify the correct kit is with: (1) a photo of the winch from above, (2) a photo of the base/model number, and (3) the size (e.g., 20/32/40, etc.).

Racing/training: frequent quick checks (smooth operation, pawl engagement sound, salt/dirt) and, depending on usage, several services per season. Cruising: thoroughly disassemble, clean, and inspect at least once a year (during winter storage); additionally, perform these checks periodically for boats in permanent mooring or those used extensively in saltwater. Always act immediately if the pawls do not engage cleanly, the winch “creaks,” or becomes stiff—otherwise, wear on the gears and bearings will increase.

Yes, provided you have basic technical skills and work cleanly. Important: Document the sequence of steps (photos), lay out parts in order, and secure small parts against falling overboard (cloth/box, preferably in port). On dinghies/catamarans, the environment is often wet/salty—so pay special attention to cleanliness. Use original parts and the lubricants recommended by the manufacturer. If load-bearing parts or gears appear damaged, it’s best to consult a specialist.

The most common mistakes: too much grease, incorrect lubricants, and dirty parts during reassembly. Clean thoroughly, let everything dry, and lubricate selectively: Never grease cleats, but only lightly oil them (otherwise they will stick). Grease gears and bearings sparingly. Make sure the cleats move freely and that everything runs smoothly without load after reassembly.

If the winch runs smoothly again after cleaning and replacing the pawls and springs, everything is usually fine. Signs that more extensive work is needed include: rattling under load, excessive play, visible damage to gears or bearings, deep corrosion marks, or a drum that no longer runs smoothly. In such cases, depending on the model, bearing or gear components may need to be replaced. A complete replacement is rarely necessary and is generally only advisable if load-bearing components are severely damaged.

Proven options include: a suitable cleaner (gentle, residue-free), winch grease for gear/bearing areas, light oil for pawls, as well as clean rags, a small parts box, and, if necessary, snap ring pliers or a screwdriver depending on the model. For commercial shipping or charter operations, a small onboard kit with pawls and springs is worth having as “emergency repair” supplies.
